Lubricant with fluorescent tracer for conveyor chains

Abstract

A lubricant for conveyor chains for bottled products that has a direct application, without dilution, to form a layer or film of lubricant on the surface of the conveyor chain, where the application is continuous at prolonged intervals between the applications, so that the lubricant for the conveyor chains can be observed under UV light in order to verify the existence and correct application of said lubricant. The lubricant is composed from 1% to 50% in weight of silicon fluid; from 5% to 80% in weight of fatty acid; from 2% to 50% in weight of amine; from 5% to 50% in weight of hydrocarbon; from 5% to 30% in weight of emulsifier; from 10% to 80% in weight of polyglycol; and from 0.001% to 10% in weight of fluorescent tracer selected from a group consisting of fluorescent whitening agent, benzoxazole thiophene, aminotriazine formaldehyde co-condensates with organic dyes, and combinations thereof.
